Neon Bulb Dim the room lights. Neutralize the plate and put it back on the charged Styrofoam plate. With the tape up, touch the free wire from the bulb while watching the electrodes inside the casing. The light produced may be weak so you may have to shadow the bulb to see the flash. Lift the plate, check that the tape rises again and touch the free bulb wire while observing the bulb. Without charging the Styrofoam, repeat placing the pie pan on and then off the Styrofoam plate, each time touching the free wire while observing which electrode lights. For each case, state whether the light emanates for the electrode connected to the free wire or from the electrode attached to the rim. Based on the results of the previous step, explain how your results are consistent (or inconsistent with the sign of the charge on the rim as determined in steps 4-6 of the instructions, assuming the Styrofoam plate becomes positively charged when rubbed with paper towels.
